Japan has had a pretty good track record with the annual Ig Nobel Prize. Scientists from all over the country have been awarded for nine years straight for their contributions to wacky and humorous research. Last year, Professor Kiyoshi Mabuchi recieved the Ig Nobel Prize in Physics for determining exactly how slippery a banana peel on the floor is.

Now, Dr. Hajime Kimata of the Osaka Prefecture Neyagawa Allergy Clinic has been given the Ig Nobel Prize in Medicine. However, rather than investigating a silly topic, Dr. Kimata’s findings were actually rather sweet: Kissing can reduce a person’s allergic reactions.

They feature so prominently in our Saturday morning cartoons and Charlie Chaplin movies that mankind has simply taken it as gospel that stepping on a banana peel will cause you to comically slip and fall with such a force that birds and stars will circle your head.

But did you know that until recently this was only a theory, unproven by a peer-reviewed scientific study? Thanks to the hard work done by Kiyoshi Mabuchi and his team at Kitasato University who were able to apply a frictional coefficient, we can unequivocally say that banana peels really are slippery when you step on them. Little wonder the group was awarded the 2014 Ig Nobel Prize in Physics.
